Description

Technical Field

[0001] The invention relates to the technical field of water meter detection, in particular to a core water-through thruster. Background Art

[0002] The existing hydraulic core water-through top clamp accessories are high in cost and short in service life, and are more difficult to implement for the installation and inspection of large-diameter water meters; the working efficiency is too low. In addition, it is difficult to detect when the seal is leaking, which has caused water pressure loss during the water meter pressure maintenance test, making the test data inaccurate; and the existing hydraulic core water-through top clamp is provided with an outer guide device, which cannot effectively offset the knob force when the meter cover knob is assembled, which can easily cause deformation or damage to the piston cylinder or the sealing ring. Summary of the invention

[0003] The embodiment of the present invention provides a core water-through pusher, which is used to solve the technical problems of the existing hydraulic core water-through pusher clamp that the sealing leakage is difficult to detect and there is no outer guide device.

[0005] Its working principle and process are as follows:

[0006] The L inner piston fixing block on the core water-passing piston assembly is fixed in the C-shaped groove of the mechanism fixing seat, and the power cylinder receives or discharges the power medium transmitted from the external power source through the power transmission pipe, thereby driving the guide clamping assembly to move back and forth on the L inner piston fixing block through the thrust connecting plate, which can prevent the piston sleeve from being fixed on the guide clamping assembly and the guide clamping assembly from doing pushing or returning movement. The piston sleeve shrinks in the guide wheel assembly, and the guide wheel assembly plays a guiding and limiting role on it, which can offset the knob force of the cover. Water flows normally inside the L inner piston fixing block and the inner piston, and the inner piston sleeve is arranged in the piston sleeve to transmit water flow outward. At the same time, water leakage between the two can be easily seen at a glance.

[0007] Furthermore, a fixed pressure plate for pressing the inner piston onto the L inner piston fixing block is provided at the connection between the inner piston and the L inner piston fixing block, and an outer circular groove is provided at the other end of the inner piston and two sealing rings are installed in the outer circular groove.

[0008] The fixed pressure plate is used to fix the inner piston, so that the inner piston is fixed more firmly on the L inner piston fixing block. Through the setting of the sealing ring, the sealing cooperation between the inner piston and the piston ferrule is guaranteed to prevent water leakage.

[0009] Furthermore, there are at least two connecting rods, one end of the connecting rods parallel to each other is fixed on the thrust connecting plate, and the other end is fixedly provided with a piston sleeve seat plate, the piston sleeve is inserted in the center of the piston sleeve seat plate, and the connection between the piston sleeve and the piston sleeve seat plate is provided with two clamping flange plates for clamping and fixing the piston sleeve on the piston sleeve seat plate, the clamping flange plates are detachably mounted on the piston sleeve seat plate, and a countersunk hole is provided at the end of the piston sleeve away from the piston sleeve seat plate, and a sealing gasket is installed in the countersunk hole.

[0010] The inner cylinder piston can be fixed by setting the piston sleeve seat plate, and the piston sleeve can be further fixed by the clamping flange plate.

[0011] Furthermore, the guide wheel assembly includes a mounting plate and two arc guide wheels which are arranged on the mounting plate and rotate horizontally. The mounting plate is arranged in a C-shaped groove, and the piston sleeve is placed between the two arc guide wheels of the guide wheel assembly.

[0012] The two arc-shaped guide wheels can limit and guide the piston sleeve.

[0013] Furthermore, it also includes a power source filter element, which is arranged on the mechanism fixing seat, and the power transmission pipe is connected to the power source filter element and is connected to the power source through the power source filter element.

[0014] The power medium transmitted from the power source is filtered through the power source filter element to ensure the purity of the power medium and extend the service life of the power cylinder.

[0015] Furthermore, a control valve mounting plate is provided on one side of the mechanism fixing seat, a control valve is mounted on the control valve mounting plate, and the control valve is connected to the power delivery pipe.

[0016] The on-off of the power transmission pipe is controlled by setting the control valve.

[0018] The provision of the power delivery pipe a and the power delivery pipe b facilitates the separate arrangement of the power delivery pipes and facilitates replacement and maintenance.

[0019] Furthermore, the end of the piston sleeve away from the vertical plate is a tapered port.

[0020] The tapered port is more conducive to docking with the water inlet of the water meter.

[0021] In summary, the beneficial effects of the present invention are as follows:

[0022] 1. The piston ferrule solves the problems of high cost, difficult procurement and short service life of the connecting hose accessories for core water flow;

[0023] 2. The power cylinder drives the clamping assembly, without the need to drive the core water piston assembly, which increases the top clamping speed;

[0024] 3. The cooperation between the inner piston and the piston sleeve makes it easier to detect water leakage and minimizes the phenomenon of loss of detection data;

[0025] 4. Adding a guide wheel assembly reduces or eliminates the destructive force of torque on the fixture components during knob assembly, making the equipment work more stable and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS
